The DRV8906-Q1, which drives the two X&Y motors and the LEDs, is tested by measuring the operating current of each of the loads while varying the input voltage from 6 V to 18 V. Additionally, the stall current of the X&Y motors and the amount of time it takes the motors to move the mirror from one end to another is measured.

Table 3-1 shows the current through the turn signal LED for input voltage of 6 V, 12 V, and 18 V. The current through the LED is much smaller at 6 V which is expected. Despite the low current, the LED turns on.

Table 3-2 and Table 3-3 shows the running current and stalling current of the Y-direction and X-direction motor for 6-V, 12-V, and 18-V input voltage respectively. The table also shows the time it takes for the mirror to travel from one end to another. In both motors, the running current and stall current increases as the supply voltage increases.
